Displaying Subscript and Superscript in Jekyll

Is it possible to represent superscript and subscript in Jekyll?

It is.

And this is not an issue with Jekyll alone, per se, but the Markdown format.

If you want to display the following:

You would key it in like this:

25<sup>th</sup> August 25, 2025

This will, hopefully, display as expected

25^th August 25, 2025

Similarly, for subscript, if we wished to display the following:

We would key it in like this:

Citation<sub>1</sub>

Which, hopefully, displays as expected:

Citation₁

Happy hacking!
